OUR histoRY
OVER 50 YEARS' EXPERTISE IN INDUSTRIAL BOILERMAKING AND GENERAL MECHANICS
Founded in 1969 by Émile Jacquier in Frignicourt (Marne), JACQUIER is a family business with cutting-edge expertise in boiler-making, piping, general mechanics and precision machining.
The company designs, manufactures, and assembles customized industrial equipment for a wide range of customers in France and abroad.
Committed to innovation and developing the skills of its employees, JACQUIER has been able to adapt and invest in new high-performance equipment to meet market trends and the needs of its customers.
Since June 2023, JACQUIER has joined the HAFFNER ENERGY group after a fruitful collaboration initiated in 2017. In particular, JACQUIER was HAFFNER ENERGY's main subcontractor for the first industrialization stage of its innovative hydrogen and renewable gas production technology. The two family-run companies have strengthened their ties over the years and have decided to give new impetus to the business, by perpetuating and developing JACQUIER's activity in the Vitryat region.
